EEL Research Highlights
Li Zhong, Robert R. Mitchell, Yang Liu, Betar Gallant, Carl V. Thompson, Jian Yu Huang, Scott Mao and Yang Shao-Horn
In this Letter, we report the first in situ transmission electron microscopy observation of electrochemical oxidation of Li2O2, providing insights into the rate limiting processes that govern charge in Li–O2 cells. In these studies, oxidation of electrochemically formed Li2O2 particles, supported on multiwall carbon nanotutubes (MWCNTs), was found to occur preferentially at the MWCNT/Li2O2 interface, suggesting that electron transport in Li2O2 ultimately limits the oxidation kinetics at high rates or overpotentials.
Watch our movies of Li2O2 oxidation: movie 1, movie 2 and movie 3.
Imaging reveals what happens during charging; could lead to improved batteries for electric cars.
